Same ol', same ol'

Nothing new to report really, just wanted to check in.  The muscle in my knee got so tight after my Thursday run last week that it hurt to even bend it, so I went for a bike ride instead on Saturday since it's lower impact on the knees.  It feels a lot better now, so I'm going to try again tonight, just gotta do some extra stretching I guess.
As for my bike ride, I ended up riding 7 miles on Saturday.  7 miles!!  Shortly after my surgery I couldn't ride halfway around the BLOCK without dying, and I'm up to 7 miles. WOW.  I thought I was gonna die on the way back though, that last 2 miles was rough, I actually had to stop and rest for a few minutes before I could make it the rest of the way home.  
I haven't lost any weight, still hovering in the 190 area, give or take a pound on any given day.  I'm guessing it's because I've been building up my leg muscles with the running. I know it's a matter of time, and I know it'll happen, just getting impatient.. it would be encouraging to see the scale move once in a while.. not just up and back down. (but at least it's coming back down lol)
I'm kinda dreading trying to run again tonight, I'm not sure if I'm cut out for running, but I'm gonna keep at it and see what happens.  If it becomes too stressful on my legs I'll just continue biking and speed walking.
That's about it!
